Strap for SuperOcean Automatic 36 Stainless Steel / White / Ruber

The Breitling Superocean A17377211A1S1 has a lug width of 18 mm. This measurement is proportional to the 36 mm case diameter and determines strap compatibility. To confirm the measurement on your own piece, use a digital calliper positioned between the lugs at the point where the strap attaches.

The ideal choice depends on context. For marine and sporting use, a vulcanised rubber strap is the most appropriate technical solution: waterproof and resistant to salt and UV exposure. For daily or formal wear, vegetable-tanned calfskin or alligator with symmetrical belly scales offer a more refined reading, enhancing the contrast between the black ceramic bezel and the stainless steel case.

Strap replacement requires a fine-tipped or forked spring bar tool, inserted into the lug hole to compress the spring bar. Work carefully to avoid scratching the case or ceramic bezel. Remove the existing strap and fit the new one with an 18 mm spring bar. The operation is fully reversible and does not require specialist tools.

Yes. The 18 mm lug width is compatible with a wide range of artisan-made aftermarket straps. Milano Straps offers straps in alligator, calfskin, rubber and NATO specifically selected for this size. Leather quality and stitching are comparable — and in some cases superior — to factory straps, with full customisation of colour, texture and buckle.

Strap longevity depends on leather quality, frequency of wear and exposure to water and perspiration. A quality vegetable-tanned calfskin strap, with moderate daily use and periodic conditioning, typically lasts 2–4 years. High-grade alligator can exceed 5 years. Leather straps should not be used for water submersion; for aquatic use, rubber or NATO straps are recommended.
